INVENTOR; osKAR EmAn UEL MEvE -snmmn BY 1 United States Patent APPARATUS FOR THE CLEANSING TREATMENT OF PARTS OF THE BODY Oskar Emanuel Meyer-Saladin, Basel, Switzerland Application February 2, 1953, Serial No. 334,446 Claims priority, appliiation Switzerland February 7, 1952 9 Claims. (Cl. 128-1731) The present invention relates to an apparatus for the cleansing treatment of parts of the body, more especially of teeth and mucous membranes of the mouth, which is characterized by the fact that it comprises a device for the production of carbon dioxide in statu nascendi and at least one orifice for the ejection of a spray, which contains the carbon dioxide at the latest upon impinging on the surface to be treated. With suitable construction, such an apparatus is particularly suitable for the treatment of teeth and mucous membranes of the mouth, when it is a question of removing this coating of mucus, which, as is known, is sticky and which forms a breeding place for all possible harmful bacteria, and particularly at places which are only accessible with difliculty, for example, at the tooth stem and between the teeth. A sufiicient removal of this film of mucus is not possible with the purely mechanical means already known, more especially the conventional tooth brush; and moreover, the auxiliary means, such as tooth pastes, tooth powders and tooth washes, used therewith, do not provide the satisfactory cleaning of the teeth which is expected of them. It is also known to employ means which can be introduced, inter alia, also in the form of a spray issuing from a nozzle, inter alia, produced by a jet of carbon dioxide, but as such means depend on industrially supplied carbon dioxide in special gas bottles, they are in practice used only by dentists while they are not sutficient for eliminating the film of mucus.

It is an object of the present invention to provide a way not only for carrying out this dental treatment more quickly and efiiciently, but which, with suitable instruction, can also be made available for use by private persons for private requirements.

The use of the apparatus of the invention is not restricted to the mouth cavity, but is also possible in gynecology and balneology.

It is to be borne in mind that the carbon dioxide adapted to be brought to the place of use is much more suitable and elfective for the present purpose than ordinary carbon dioxide, such as can be obtained, for example, from the commercially available carbon dioxide bottles. By suitable construction of the apparatus of the invention and suitable choice of the chemical components from which the carbon dioxide is produced, it is also possible by selective and successive treatment of the surfaces by these components alone to produce a more eifective treatment or initial treatment, so that to a limited extent it results in a formation of carbon dioxide in statu nascendi at the immediate place of use, that is to say, on the surface which is to be treated itself, the said surface being still covered by the component previously used when the second co ponent is subsequently applied to the surface.

Some embodiments of the invention are shown by way of example in the accompanying drawing in which:

As will be seen from Figure 1, an apparatus according to the invention comprises a stationary housing which is provided with an upper triangular flange 1 and a lower rectangular flange 2 which form the rearward closure of the housing and which are provided with bores 3 by means of which the housing can be screwed on to a wall. The housing comprises a tank 4 for gas under pressure, said tank being connected through a non-return valve to a hand pump 5 which serves to produce the gas under pressure. The hand pump is in the form of a conventional hand-operated piston pump, such as is used, for example, as a bicycle pump. The non-return valve has a conical seating 6 in a short pipe 7 projecting into the tank 4. Cooperating with the valve seating 6 is a valve ball 8 which is urged against the seating 6 by spring means, such as a compression spring 9, held under the required initial tension by a grub screw 10 screwed into the pipe section 7. The pipe-section is formed with apertures 11 which open into the tank 4.

' It is obvious that any other suitable valve, for example a conventional tire Valve as used with bicycle and motorcar inner tubes, can be employed instead of the valve which is illustrated. The housing section 12 the tank 4 is in the form of a horizontal plate 13, which, together with the y, the 'manner of a fitted lid. Disposed between the edge: of the container 14 and the plate is a packing ring 15 of elastically yieldable material. As will be seen fIOlll. Figures 1 and 2, the casing of the container is providedi with three projections 16 which project radially outwards and which each engage in an annular groove formed in the inside of the ring 13. This groove has a horizontal portion 17 and a vertical portion 18, which latter is led up to the free edge of the ring. These portions 17 and 18 together with the projection 16 form a bayonet joint which, in the engaging position illustrated, urges the edge of the container 14 hermetically against the packing ring 15.

Arranged inside the container 14 are two fitted cups 19 and 20 which are semi-circular in cross-section and which are seated in the container with only small clearance and with their flat boundary surfaces bearing freely one against the other. They are disposed with their bases on the bottom of the container and are of such a length that their edge with the opening is pressed against the packing ring 15.

Patented Aug. 7, 1956 adjoining; which is. provided with a downwardly projecting annular holder' plate section enclosed therethen surrounds the upper part of a container 14 in:

The flat boundary walls of thetwo cups are provided in their upper portions with orifices 21 adjoining one another.

The part 12 of the housing comprises a horizontal duct .22 whichopens at one end into the tank 4 and at the other end into a vertical bore into which is tightly fitted a pipe 23. The pipe 23 extends through the housing wall 24 of a shut-off valve, the plug 25 of which is provided at this point with openings which can be seen in Figure 1. The housing 24 is perforated by a connecting pipe 26 on the diametrically opposed side of the plug 25. In addition, a pipe 27 is connected to the valve at an angle to the pipe 23, this pipe 27 being led through an opening in the housing part 12 and the washer 15 and opening into the uppermost part of the cup .19.

The part 12 of the housing is formed with two further vertical bores, through each of which is passed a liquid pipe 28, 29. The pipe 28 dips in the form of a riser into the cup 19 and terminates close above the bottom of the latter In a similar manner, the liquid pipe 29 is immersed as a riser in the cup 20. The pipes 28 and 29 are passed through the housing wall 24 of the same valve as the gas pipe 23 but at an axially displaced position of this valve, at which the plug 25 has the shape which is shown inFigure l and which has eccentrically disposed ,passages 30 and 31 respectively. Simply for the purpose of clearer representation, three separate valves or cocks are shown diagrammatically in Figure 1. In actual fact, it is only necessary to use one and the same shutoff valve, having ditferent cross-sections at axially spaced positions. However, there is nothing to prevent three separate shut-off valves being provided in accordance with the layout according to Figure 3, instead of a common plug 25. In alignment with the pipe 28 on the opposite side of the valve is a liquid pipe 32, and connected in a similar manner in alignment with the pipe 29is a liquid pipe 33. As will be seen, all the pipes are closed when the plug 25 is in the position shown in Figure 1. However, if the plug 25 is turned through 90 in the direction of the arrow so that it assumes the position shown in Figure 3, then the pipes 23, 26 and 27 for the gas under pressure are connected with one another. Furthermore, the liquid pipe 28 is connected by the duct 30 with the liquid pipe 32. Similarly, the liquid pipe 29 is connected by the duct 31 with the liquid pipe 33. The pipe 26 is connected at its other end to a chamber 34 which is disposed in a hollow handle 35 and is forked into two mixing chambers 36 and 37. Each mixing chamber 36 comprises a discharge orifice constructed as an injector nozzle 38, 39, said said-nozzles leading into a combined mixture chamber 40 formed by the conically terminating portion of the handle element 35. Connected to the conical portion of the handle element 35, is an outlet tube 41 to which there is detachably secured, by means of a bayonet joint 43, a hollow brush 42 intended for operating on the surface to be treated.

Located in each of the liquid pipes 32 and 33 is a flow control member which is adapted to be operated by the pressure of a finger on a button 44, 45 against the influence of a return spring 46 in each case. The return springs 46 are each disposed in a transverse duct which crosses the pipe 32 or 33 and are mounted at one end on the nozzle and at the other end against the inner end of a control slide 47, 48 which is displaceable 'longitudinally in the transverse bore. The control slide 47 carries the button or knob 44 at its free end and is provided with a control bore 49 parallel to the pipe 32. In a similar manner, the control slide 48 carries .the knob 45 at its free end and has a control bore 50.

In the position shown in Figure l, the control slides 47 and 48 are disposed in the closed position which is ensured by the force of the return springs in which position the pipes 32 and 33 are completely shut ofi. By

pressing on the knob 44, the control slide 47 is displaced towards the right so that the control bore 49 uncovers the passage through the pipe 32. When the knob 44 is in the fully pressed-in position, the entire cross-section of the pipe is uncovered by the bore 49. The same result is obtained with the controlslide 48 upon pressing in the knob 45, as regards the pipe 33 and the control bore 50.

The end of the pipe 32 which is connected to the control member is introduced into the single mixing chamber 36 of the handle element 35 and is constructed as ,an injector nozzle 51. In a similar manner, that end of the pipe 33 following the control member is introduced into the single mixing chamber 37 and formed as an injester nozzle 52.

in Figure l, the control member and the liquid pipes 32 and 33, and the pressure gas pipe 26 are only shown diagrammatically. In practice, in the particular embodiment, as will be seen from Figures 4 to 10, the control members and all the pipes are fitted into the handle element 35, the two control members being staggered and arranged turned by relatively to one another, so that the control slide 47 in the position shown in Figure 4 is adapted to be pushed inwardly by pressure acting in the transverse direction, whereas the control slide 48 is adapted to be forced in by a force on the knob 45 which encloses an angle of 90 with the direction of the control slide 47. As shown in Figure 4, the handle element is constructed as an elongated part of the apparatus which is adapted to be gripped in the hand of the operator and comprises, considered in the direction of flow, the forward end of the apparatus including the two control members, which are so arranged that each control member is disposed in a region suitable for the operating finger of the hand gripping the handle element. By suitable choice of dimensions, the operation of the control members can easily be efiected by the thumb and index finger or middle finger of the hand gripping the handle element. As will be seen from Figure 4, the part of the apparatus connected to the handle element 35 is formed as a flexible tubular element 53, for example, in the form of a hose, which encloses the pressure gas pipe 26 and the two liquid pipes 32 and 33. The connection part 54 can be made in the form of a nut or bayonet joint or the like so that the handle element is connected with the tubular element 53 in a readily detachable manner.

Inuse, the container 14 is first of all turned manually in the direction of the arrow shown in Figure 2 until the projections 16 pass into the vertical groove 18, whereby the bayonet joint is released and the container can be drawn downwardly together with the cups l9 and 20 located therein. An acid-containing liquid component is then introduced into one cup, for example into the cup 19, while a basic liquid component containing a carbonate or bicarbonate is introduced into the other cup 20. The acid-containing component may for example contain tartaric acid or lactic acid, and also a fruit aroma and a sweetening substance, and perhaps also a vitamin supplement, more especially vitamin C. The basic component may contain sodium bicarbonate or sodium carbonate, perhaps mixed with suitable aromatic substances. The container 14 with the cups is then fitted again by operating the bayonet joint. The shut-0E valve 24, 25 isdisposed in the closed. position illustrated in Figure l. The-pressure gas, for example compressed air, is next produced -by operating the pump 5, until the tank 4 has the required pressure. The plug 25 of the shut-otf member is then rotated intothe open position shown in Figure 3, ao-that first of all gas under pressure passes into the space disposed above the liquid in the cup 19 by way of the passage 22, pipe 23 and pipe 27. Owing to the provision of the openings 21, the space above the liquid in thecup 20. is also filled with gas under pressure, so that the acid liquid component can pass into thepipe 32 by way'of the pipe 28 and the duct 30, but imp! vented from fiowingthrough the control member 47 which is in the closed position. The basic liquid component, which ,canpass .by way of the rising pipe 29 and the duct '31 into the pipe 33, behaves in a similar manchambers 36 and 37,

ner, but is prevented from flowing through member 48 whichis in the shut-ofl position. M On the contrary, the pressure gas pipe 26 is completely open after the shut-ofi'member 24, 25 has been opened, so that gas under pressure can pass through the pipe 26 and through the chamber 34 into the two separate mixing and through the injector, nozzles 38 and 39, the combined mixing space 40, the outlettube 41 and the hollow brush 42 to atmosphere. Disposed in the vicinity of the nozzles 38 and 39 are air-holes 55, which permit the entrance into the combined mixing chamber 40 of outside air which is drawn in by injector action.

The operator then grips the handle element, and ad vauces .it 'to the surface to be treated with the hollow brush 42 or with the outlet tube 41 when the brush is removed. At the same time, he pushes in the pressbutton 44 so that the acid liquid component can flow through the pipe 32 and pass through the nozzle 51 into the single mixing chamber 36 which is in communication by means of openings 56 with the outside air so that outside air can be drawn in at the same time by the injector action. The liquid is atomised in contact with the pres sure gas flowing through the mixing chamber 36 and converted into a fine spray which passes through the injector nozzle 38, the chamber 40, the outlet pipe 41 and brush 42 to the place where it is to be used and there effects a loosening and partial washing-away of the mucous layer covering surface. p

At the same time, the operator can with the other hand draw the lips somewhat away from the teeth so that all places can be covered by the brush, which is moved accordingly; As a result of the pressure, the spray also reaches the gum cavities and the interstices of the teeth the control which are only accessible with difiicult y. The spray removes the chemically dissolved parts of mucous form, the fine bubbles of the spray being charged with the dissolved mucousparticles and carrying these away.

Thereafter, the press-button 45 is also pressed in, this" permitting the flow of the basic liquid component through the pipe 33. The said component passes through the nozzle 52 into the single mixing chamber 37 which is in communication by means of openings 57 with the outside air fordrawing in supplementary air by injector action. The basic spray is now formed in the single mixing chamher 37, said spray issuing by way of the injector nozzle 39 and impinging on the acid spray leaving the injector nozzle 38. By contact of the two sprays, there .takes place a decomposition of the carbonate or bicarbonate of the basic component by the acid of the acid component, which leads to the formation of carbondioxide in suitable quantities. This carbondioxide is led immediately after it is formed or while it is being formed through the combined mixing chamber 40, the outlet pipe 41 and the brush 42 to the place of use, or perhaps is only formed at the said place. The cleaning of the surfaces to be treated is completed with this carbon-dioxide spray. Thereafter, by releasing the press-button 44, the acid component must be shut-off and a subsequent neutralisation of the treated surfaces of all acid residues must be produced with the basic component alone. By this means," a salivation is produced in the mouth which encloses and protects the teeth. This basic saliva prevents the growth of harmful bacteria. i

. There is nothing to prevent the treatment being carried out with the brush 42 removed or alternately with the i brush and without the brush.

In contrast to the arrangement shown in the drawing, it is possible 'in a particular construction to dispense with the foremost conical position of the handle element 35 so that the injector nozzles 38 and 39 lead directly into atmosphere and can be brought directly to the place of treatment. v The effect obtained in this manneris that the carbon dioxide is formed directly at the place where it is used or directly before impinging thereon. I Iere also It is not absolutely necesary,"to fit the brush 42 in the I form of a hollow brush directly on the outlet pipe 41 as shown in Figure 1. It is, in fact, also readily possible for a brush having a handle of suitable length of be detachably fitted on the handle element adjacent the outlet pipe 41. For this purpose, the handle element may for example be provided with a suitable bore which is par allel to the outlet pipe 41 and which does not extend into the housing, or with clips in which the handle of the hand brush is adapted to be fitted as a tight fit. Preferably, the hollow brush is so constructed and arranged that it is disposed in the immediate vicinity of the orifice of the discharge pipe 41 or that the outlet pipe 41 extends into the brush between the bristles thereof so that the spray issuing from the said'pipe 41 reaches that region of the object undergoing treatment which is operated on by the bristles.

In contrast to the arrangement shown in Figure l, the pump and "vessel assembly or, with omission of the pump, the vessel assembly including the shut-off valves can be provided with a base instead of with a device for hanging it on the wall, said base enabling the apparatus to be set up directly on a table.

As will be seen from Figure 11, the foremost part of the apparatus, considered in the direction of flow, is formed with a handle element 61 adapted to be gripped by the hand of the operator as in the preceding construction. The part of the apparatus connected to'the handle element 61 is'again formed as a flexible pipe element 53 which is in the form of a hose and which encloses two liquid pipes 32 and 33 and the pressure gas pipe 26. The two liquid pipes 32 and 33 and the pressure pipe 26 may each be fed by a liquid container or a source of pressure gas, in the same manner as indicated in Figure 1, but each pipe will comprise a separate shut-off member so that it can be independently regulated and shut-off.

In the present case, flow-control members in the handle element itself are dispensed with, although there is nothing to prevent such flow-control members from shutting-cit and regulating at least one liquid pipe being provided in the handle element. I

According to Figure 11 of the drawing, the three pipes 26, 32 and 33 are shown purely diagrammatically as being connected to a longitudinal bore provided in the handle element 61. The longitudinal bore following the pressure gas pipe 26 in the handle element forms the pipe 62, whereas the longitudinal bores connected to the liquid pipes 32 and 33 form the pipes 63 and 64 respectively. All pipes extend parallel to one another longitudinally of the handle, the two liquid pipes 63 and 64 being disposed symmetricallyof the radial axial plane XVI-XVI passing through the axis of the pressure gas pipe 62, as shown in Figure 14.

As will now 'be seen more particularly from Figure 12,

' the discharge end of the handle element 61 is conical and narrow cone, "are indicated by reference 62, 63 and 64'.

As will now be seen more especially from Figures 15 to 17, the cone 65 is formed with a longitudinal groove following each pipe outlet. The longitudinal groove following the outlet 62' is indicated at 66 (see Figures 16 and 17). The longitudinal grooves following the openings 63' and 64 are indicated at 67 and 68 respectively in Figure 15. The longitudinal grooves 66, 67 and 68 extend asfar as the free end of the cone 65 and are shown excessively deep for the purpose of better illustration in the drawing. In actual fact, groove depths of the order of size of a tenth of a millimetre'are sufficient for practical requirements.

As will be seen from Figure 11, the cone 65 is now enclosed by a conical casing 69 having thesame eonicity, said casing bcingshown in Figure 13. For the purpose of securing the conical casiug 69, the cone is provided with a threaded extension (Figure 12) at a point disposed in front of the pipe openings 62', 63', 64/, when considered in the direction of flow, the conical casing 69 formed with a female thread 71 at the base end being screwed on to said extension 70. In Figure 13, the conical casing is shown bearing flush on a shoulder 72 of the handle element directly below the thread 70. In this position, the inside of the conical casing bears without play on the cone 65, so that each groove 66, 67 or 68 of the cone is limited on the outside directly by-the position of the conical casing 69 which faces it, and each groove forms with the corresponding part, of the conical casing a nozzle duct which leads to atmosphere. The outlets 62', 63 and 64' are closed by those parts of the conical casing 69 which are opposite them, so that therefore the pipes 62, 63 and 64 open directly into the corresponding nozzle ducts.

If the conical casing 69 is now turned in the unscrewing direction relativelyto the cone 63, this results in an axial displacement of the conical casing 69 forwardly with respect to the cone 65,, said displacement corresponding to the pitch ofthe screwthread. By this means, there is formed a corresponding clearance between the inside of the conical casing and the cone which in practice results in that the nozzle ducts are somewhat larger in cross-section than the bare cross-sections of the grooves 66,67 and 68. The nozzle ducts are however formed on ,the inside by a part of the cone and on the outside by a part of the conical casing, it having been shown in practice that it is of no importance if the nozzle ducts partially merge into one another owing to the saidclearance between the cone and conical casing. This isall the more the case if the grooves, measured in the peripheral direction are disposed relatively far apart and the said clearance between the cone and conical casing only amounts to extremely small amounts, so that the increase in nozzle crosssection is of considerable effect for the total flow crosssection, but not as regards the overflow conditions from one duct tothe other in the peripheral direction disposed transversely of the flow direction proper. The threaded extension 70 and the female thread 71 are made as fine threads and exactly fit one another so that in the tightly screwed position, the screw thread has a sealing effect against an unintentional back pressure of the pressure gas or of the liquids under pressure from the outlets 62', 63', 64', regardless of whether the conical casing 69 is tightly screwed until bearing firmly on the shoulder 72 or is slightly slackened off for regulating. the nozzle cross-see tion.

As will be seen more particularly from Figure 17, the cone 65is formed with two additional and substantially deeper grooves 73 and 74 which connect the pressure gas pipe 62 at the, commencement of the outlet 62 with the outlet 63 and 64 respectively of the liquid pipes 63 and 64. With the conical casing 69 screwed up, the pressure gas pipe is connected by a passage with each of the openings of the two liquid pipes, the wall of which is formed on the inside by a part of the cone and on the outside by a part of theconical casing, so that again, when the conical casing 69 is tightly screwed in position, the grooves 73 and 74 limit the passage on the inside and that part of the conical casing which is opposite the grooves limits the passage on the outside. In this case also, by partially unscrewing the conical casing .69, the corresponding passage cross-section is somewhat var ied. However, this is of lessimportance, as in this case it is a question of much deeper grooves than the case where the grooves 66, 67and 68 were concerned, sothat the axial displacement of the conical casing 69 to the extent to be expected in practice, has no-effect on the flowconditions. From the outlet 62 of the pressure gas pipe, the grooves 73 and 74 extend forward he1icallY,:so that the pressure gas which in use comes from'the pipe 62 and flows through said grooves exerts an injector-hire suction effect on the liquid supply at the opening into the liquid pipes 63 and 6 4 and the nozzle ducts 67 and 68 andeffects the formation of the spray. When used in practice, when the shut-0E members of the pipes 26, 3 2 and 33 are all opened, and pressure gas is flowing through thepipe 62 and a basic liquid component and an acid liquid component, both under pressure, flow respectively through the pipes 63 and 64, a fine jet of pressure gas or jet of liquid spray issues through the corresponding nozzlc ducts 66 and 67 and 68, respectively, all the jets uniting outside the conical casing 69 at the truncated theoretical apexof the cone and the spray, united at this point with formation of nascent carbon dioxide, impinges upon the object undergoing treatment.

Preferably, the handle element comprises an axial bore, (not shown), or two hollow members for fitting the handle of a brush associated with the theoretical apex of the cone. This brush can be so constructed and arranged that the bristles bear directly at the forward end of .the conical casing 69. The bore can therefore also be provided directly on the conical casing 69 or the brush can be secured in a detachable manner on the conical Contrary to .what is shown in the drawing, it is obviously also possible to secure the conical casing to the cone other than by means of the threaded extension 79 and the female thread 71, whether it he by a different type of screw-threaded arrangement or method of fixing. It is also readily possible to carry out the axial adjustment of the conical casing relatively to the cone in a manner other, than in conjunction with a rotation of the conical casing relatively to the cone. .It is therefore possible tocarry out a purely axial displacement, using known auxiliary means which are in everyday use by the expert for such purposes. More particularly such a case, it is readily possible to dispense with the grooves 66, 67 and 68 or 73 and 74 in the cone and to provide instead corresponding grooves on the inside of the conical casing, or more especially for the grooves, there can be used a combination between grooves in thecone and grooves in the conical casing which are mutually increased in size.
